Olympia's Toadliquor have been peddling some of the ugliest and most oppressive sludge-doom the Pacific Northwest has produced since their 2003 formation, dragging out riffs to their most suffocating extremes against a backdrop of feedback and misanthropy.

Chattanooga newcomers Toadsmoke formed in 2023 with a filthy hybrid of death metal and sludge, piling on the Tennessee muck with riffs that lurch and churn with equal parts grime and violence.

Denton's Todopoderoso, assembled in 2023, push progressive and sludge metal into unexpected territory, blending North Texas's vibrant experimental music scene with the genre's heaviest and most challenging structural tendencies.

Seattle's Toilet Boys, assembled in 2024, wade through a particularly grimy mix of sludge and death metal — caustic, bottom-heavy, and carrying the city's long history of ugly, confrontational music into the present.

Wilmington, North Carolina's Toke have been delivering fuzz-drenched, smoke-soaked sludge and stoner metal since 2015 — the kind of slow, heavy music made for maximum volume and minimal sobriety, built from the coastal South's laid-back heaviness.

Butler, Pennsylvania's Tombless emerged in 2023 merging death metal's ferocity with sludge metal's weight, dragging tempos down through tar-thick riffs while maintaining enough savagery to keep the material fully in extreme metal territory.

Greenville, South Carolina's Tone S.T.S. have been channeling black metal's hatred and sludge metal's oppressive slow burn into a unified, filth-encrusted sound since 2015. The combination suits the isolation of the Upstate South, where atmosphere and weight converge into something genuinely suffocating.

Kissimmee, Florida's Tooms emerged in 2018 grafting groove metal's hip-swinging heaviness onto a metalcore skeleton, resulting in the kind of melodic, rhythmically locked sound that translates well in a live setting. Their MA genre tag of "melodic groove metal/metalcore" captures the balance precisely.
